There is no universal separable Banach algebra

Kania, Tomasz

We prove that no separable Banach algebra is universal for homomorphic embeddings of all separable Banach algebras, whether embeddings are merely bounded or required to be contractive. The same holds in the commutative category. The proof is short and direct. For each closed subspace $X$ of $c_0$ we build a separable c...

The analytic method of constructing local-in-time solutions of the incompressible Euler equations in Sobolev spaces

Kukavica, I. · Ożański, W. S.

We introduce a new method for constructing local-in-time solutions of the incompressible Euler equations in Sobolev spaces on an arbitrary Sobolev bounded domain. The method is based on a construction of an analytic solution in an analytically approximated domain, after which we apply analytic persistence to extend the...

Operando BCDI for observing the phase transformations in single particles of LMFP cathodes.

Yuhan LIU · Alice LLEWELLYN · George PHILLIPS · Steven LEAKE · y 2 más

BCDI will allow us to obtain high-resolution 3D reconstructions of individual crystals of industrially relevant, state of the art electrode materials during operation. Performing these experiments operando will give data about the evolution of strain during cycling, directly relating them to the electrode’s electrochem...

Asymptotic solutions for the modal properties of shallow cables with small bending stiffness and compliant supports

Corazza, Stefano · Foti, Francesco · Denoël, Vincent

Metallic cables are key components of large and strategic infrastructures, such as suspension and cable-stayed bridges, and are also adopted in many special structural applications, including cable-roof systems and slender footbridges. Monitoring the cable axial force, possibly together with other relevant structural p...

Collaborative Analysis for Paired A/B Testing Experiments

Zhang, Qiong · Kang, Lulu · Deng, Xinwei

With the extensive use of digital devices, online experimental platforms are commonly used to conduct experiments to collect data for evaluating different variations of products, algorithms, and interface designs, a.k.a., A/B tests. In practice, multiple A/B testing experiments are often carried out based on a common u...

In situ dehydration of the uranium mineral studtite: a variable temperature U M4-edge XAS and XES study.

Elena BAZARKINA · Bob BAKER

The dehydration of studtite [UO2(O2)(H2O)2].2H2O is complex but goes through an X-Ray amorphous phase, whose structure is unknown, but possibly U but Possibly U2O7. Importantly it has been the cause of accidents in waste storage facilities. This project aims to explore the dehydration in an in-situ experiment at the U...

Retrievable “sea-island” microstructured zwitterionic-silicone hydrogel devices: augmented oxygen transport and anti-fibrosis for sustaining islet survival

Danyang Chen · Hongying Wang · Yipeng Tang · Jinghui Li · y 10 más

Islet encapsulation is a transformative strategy for type 1 diabetes (T1D) cellular therapy, enabling islet transplantation without lifelong immunosuppression. However, macroscale encapsulation faces prominent challenges: poor surgical retrieval, hypoxia, and foreign body response (FBR)-induced fibrosis, which severely...

System-Wide Patterns of Costs and Service Use Among Frequent Emergency Department Users in the United Kingdom

Mattock, R. · Bojke, C. · Saraiva, S. · Relton, S. · y 11 más

We estimate healthcare costs and service utilization for frequent users (FUs) of emergency departments (EDs) compared with non-FUs across the urgent care pathway, using regional UK data. Recognizing FU heterogeneity and differences in service models, we examine cost variation by patient characteristics and across healt...

Genetic and province-scale relationships of alkaline leucogranite-foid syenite in the Haruchas Dual Complex (South Namibia)

Jorge C.L. Arthuzzi · R. Johannes Giebel · Michael W. Marks · Aratz Beranoaguirre · y 10 más

The Haruchas Dual Complex in southern Namibia is part of the Richtersveld Suite and formed by two stocks that comprise coexisting silica-oversaturated alkaline granite and silica-undersaturated foid syenite, respectively. This contribution integrates mapping, petrography, whole-rock and mineral geochemistry, and U-Pb g...
